Geotechnical considerations underground audit – guide Page 2 of 41 Introduction This document was completely revised and reformatted in November 2015. This was a material change to the content of the guide to closely align this audit with the Geotechnical considerations open pit audit.Underground mining can be considered to be more acceptable than surface mining from environmental and social perspectives since, it often has a smaller footprint than an open-pit of comparable capacity. The main advantage of underground mining compared to surface mining is that in general only the ore is extracted and waste rock is left behind.
